  • Effect of bundled care on postoperative nausea and vomiting in patients undergoing day laparoscopic cholecystectomy

    Objective To explore whether bundled care for anesthesia management can reduce the risk of postoperative nausea and vomiting (PONV). Methods The data of laparoscopic cholecystectomy patients admitted to the Day Surgery Center of West China Hospital, Sichuan University between July and November 2021 were retrospectively collected. Patients were divided into a bundled care group and a control group based on whether anesthesia management was implemented according to the bundled care. The demographic characteristics, intraoperative anesthesia management methods, postoperative conditions, and incidence of PONV between the two groups of patients were analyzed and compared. Results A total of 314 patients were included. Among them, there were 124 cases in the bundled care group and 190 cases in the control group; PONV occurred in 52 cases, the incidence of PONV was 16.6% (52/314). Except for surgical time and postoperative incision infiltration (P>0.05), there were statistically significant differences in age, gender, body mass index, anesthesia time, airway establishment, and postoperative analgesic use between the two groups of patients (P<0.05). There was no statistically significant difference in the occurrence of PONV between the bundled care group and the control group (17 vs. 35 cases; χ2=1.205, P>0.05). The results of logistic regression analysis showed that PONV was correlated with gender [odds ratio=0.107, 95% confidence interval (0.030, 0.375), P<0.001], and using bundled care [odds ratio=0.388, 95% confidence interval (0.169, 0.894), P=0.026]. Conclusions Women are at high risk of PONV among patients undergoing day laparoscopic cholecystectomy. The risk of PONV is lower when using bundled care.

  • Off-Label Drug Use in Outpatient Children: A Systematic Review

    Objective To assess the global situation of off-label drug use in outpatient children.Methods A search was conducted in PubMed, EMbase, CBM, CNKI and VIP for collecting studies on off-label drug use in outpatient children aged 0 to 18 years, and the publication language was limited to English and Chinese. The quality assessment was based on Crombie Criteria for cross-sectional studies, and the descriptive analysis was performed to analyze the incidence of off-label drug use at all levels of medical institutes and different age groups, the common types of off-label used drugs, and the constitution ratio of off-label use drugs. Results A total of 20 cross-sectional studies were included, involving 1 933 760 children and 5 262 573 prescriptions. The results of descriptive analysis showed: a) The incidence of off-label drug use in outpatient children in primary care and tertiary care institutes were 19.5% (IQR 13.5%, 24.5%) and 26.0% (IQR 24.0%, 35.0%), respectively; b) The primary studies reported that neonate, infant and adolescent had the highest incidence of off-label drug use, while the other children had the lowest incidence; c) Drugs for respiratory system, anti-infection, sensory organs, and dermatosis were listed as the top 5 frequently used off-label drugs by more than half of the studies; d) The studies with issue of “lack of instruction for children” showed it was exactly the type with highest incidence of off-label use, while other studies without that issue showed the highest incidence was over aged off-label use. Conclusion a) Off-label drug use is common in outpatient children. The incidence of off-label drug use may be higher in tertiary care institutes than primary care institutes, and it is higher in neonate, infant and adolescent rather than other age groups of children; b) Incidence of off-label use may be higher in inpatient children than outpatient ones; c) Drugs for respiratory system, anti-infection, sensory organs, and dermatosis were most common types of off-label use; and d) Off-label use due to both “lack of instruction for children” and “over aged use” is more common. So it suggests that further studies trials should focus on fields in which clinical trials of drugs are totally absent.

  • Off-label Drug Use in Hospitalized Children: A Systematic Review

    Objective To assess the global situation of off-label drug use in hospitalized children. Methods The databases such as PubMed, EMbase, CBM, CNKI and VIP were searched to collect studies on off-label drug use in hospitalized children at age of 0 to 18 years old. The publication language was limited to English and Chinese. The quality assessment was based on Crombie Criteria for cross-sectional studies. The incidence of off-label drug use was described in different wards and age groups, and the proportion of different off-label used drugs was analyzed. Results The total 29 cross-sectional studies were included, involving 8 560 children and 41 655 prescriptions. a) Median (IQR) of off-label use incidence: Neonatal ICU 52.5% (23.0% to 44.8%), Pediatric ICU 43.5% (34.5% to 60%), General pediatric ward 35.5% (23.8% to 43.3%), Pediatric surgical ward 27.5% (23.0% to 44.8%); b) The results of off-label incidence in different age groups were inconsistent among different studies; and c) The off-label drug use for “no pediatric information” had the largest proportion, followed by dose and age. Conclusion a) Off-label drug use exists widely around the world, but the incidence varies a lot in different countries and different types of wards; b) The incidence of off-label drug use may be higher in ICU than in non-ICU, and higher in the neonatal ward than the pediatric ward; c) The off-label drug use for no pediatric information is the commonest type, and further clinical studies should focus on areas in which high quality evidence is totally absent; and d) The multi-center studies with unified design on off-label drug use in hospitalized children in China are urgently needed to provide evidence for policy-making.

  • Evidence-Based Evaluation on Off-Label Drug Use Policies in 15 Countries

    Objective To evaluate the related laws, regulations and guidelines about off-label drug use in several countries, so as to provide evidence for regulating off-label drug use in China. Methods The following 3 Chinese databases as CBM, CNKI and VIP, 11 foreign databases including EMbase, PubMed and so on, 15 countries’ official websites of pharmaceutical administration department or academic organization, and WHO website were searched to obtain the related laws, regulations and guidelines about off-label drug use. By adopting the system evaluation method and self-defined index evaluation, the quality of the included literatures was evaluated in three aspects: literatures’ type, content relevance and timeliness. Seven researchers independently extracted data by Excel which included basic information of literatures, preconditions of off-label drug use, medicines categories that could be off-labelly used, regulations and legal responsibility in off-label drug use. And finally the descriptive analysis was conducted. Results A total of 4 735 literatures were retrieved, 104 of which were finally included, including 89 at grade A quality level (85.58%) and 15 was at grade B (14.42%). The analysis showed that, a) Seven countries had laws related to off-label drug use: America, Germany, Italy, Netherland, New Zealand, India and Japan. Except India, the rational off-label drug use was allowed in the other 6 countries. The right to prescribe off-label drug was defined in Britain and Ireland; b) Medical staff had to take the responsibility of off-label drug use in the country where the duty regulations were formulated; and c) Ten countries published guidelines or statements related to off label drug use by their official departments and academic organizations. And the regulation included the following procedures: firstly, to obtain the relative information and evidence; secondly, to get the informed consent; thirdly, to be approved by the ethics committee and/or pharmacy administration committee; fourthly, to record the reasons and effectiveness of off-label use; fifthly, to monitor the adverse reactions of off-label drug use. Besides monitoring the medical institutes, the pharmaceutical companies had also be monitored which included the following 3 aspects: a) to require companies to train specialized staffs to answer the questions related to off-label drug use; b) to open the contact information of medical departments of companies; and c) to prohibit preaching and advertising the off-label drug use. Conclusion Off-label drug use has its rationality and necessity. To protect the safety of patients, avoid the risk for hospitals and medical staffs, it requires formulating relative regulations soon in order to manage the off-label drug use in China. As a developing country, China is different from the developed countries in health care system. Therefore, when formulating the regulations, it is necessary to perform evidence-based evaluation on each country’s laws, regulations and guidelines about off-label drug use, with Chinese national conditions and experts’ opinions in combination. After a regulation is preliminarily drawn up, it needs to be put into pilot practice, and then revised and spread to the whole country.

  • Effect of Drug Management Skill Training on Lightening the Family Burden of Schizophrenic Patients in the Recovery Period

    ObjectiveTo explore the effects of drug management skill training on lightening the family burden of schizophrenic patients in their recovery period. MethodsBetween December 2011 and December 2013, 101 patients with schizophrenia were randomly divided into experimental group (n=56) and control group (n=45). The experimental group was given drug management skill training, while the control group only received routine follow-up. The course of the research was six months. Both groups were assessed by the positive and negative syndrome scale on patients' psychological symptoms, and family burden scale of diseases was used to assess the burden of the family. ResultsCompared with the controls, patients in the experimental group improved more in their positive symptoms (t=2.692, P=0.008), negative symptoms (t=2.729, P=0.008), general psychopathology symptoms (t=3.231, P=0.002) and the whole psychiatric symptoms (t=3.870, P<0.001). Moreover, the degree of patients' symptom improvement was positively correlated with the degree of family burden lightening (r=0.44, P<0.001). ConclusionFor patients with schizophrenia, reasonable drug management skill training can effectively improve patients' medication compliance, promote treatment effect and lighten family burden.

  • Comparative Study of Developing Methodologies of Essential Medicines Lists for Children Worldwide

    ObjectiveTo evaluate the developing methodologies of Essential Medicines Lists for Children (EMLcs) in global, in order to provide reference in developing EMLc of China. MethodsWe searched ProQuest, ScienceDirect, SpringerLink and MEDLINE databases, World Health Organization (WHO) official website, and 67 websites of National Ministry of Health and Drug Administration Section, to collect literature about selection methodology of children and/or adult essential medicines list (EML). A descriptive analysis was conducted. ResultsA total of fourteen literatures were included. Of which, 6 were about the essential medicines selection methodology in children, and the other 8 were about the essential medicines selection methodology in adult. The WHO had established independent EMLc selection committee. Paediatricians were involved in the selection of EMLc in the WHO and India. There was no selection criteria and process for EMLc globally. The WHO, India, and South Africa selected their EMLcs referring to the WHO EML selection criteria. The WHO and South Africa had their own updating time, period and process for EMLc. The WHO EMLc was updated per 2 years, which in high frequency and conducts in rigorous process. However, the EMLc of India had not been updated yet. ConclusionIt is suggested that China could build a national EMLc selection committee involving paediatricians and evidence-based medicine experts etc. in referring to the framework of the WHO Child Health Working Group. The EMLc selection criteria and process of China could be established referring to the one of the WHO, based on the disease burden, drug accessibility and medical insurance of children of China. The EMLc of China should be simultaneously updated with the adult EML of China.
